From my understanding I need some cubemaps to make things like the pistons and metal walls look nice and shiny.
Cubemaps
When you finish making your map, just open it in hl2dm and type into the console: "buildcubemaps" and it'll compile it for you, then shoot it over to Portal.
That's what I've been doing. It just crashes in Portal because... Well, I dont know why, but it does just crash, so try it in HL2DM.
when I used it, it seemed to work fine on my level.
Ralph, when you process it in Portal, does it screw up the controls really bad? like if you try to walk around, does it have you all restricted to where like one or two of the directional keys work and the mouse goes dead? That's what mine did when it got that error.. Almost scared me out of even working with the editor until the sdk got brought up, but i just kept fighting along.
I tried it in HL2, that didn't work because it didn't have the textures, so I finally did it in the portal 'mod' I created when setting up the SDK, this worked fine. Copied the BSP back and enjoyed ma cubemaps in portal.
Take note that recompiling the map will delete the existing cubemaps, hence you should make building cubemaps the last thing you do before releasing the map.
Restart steam to update, and cross your fingers. :0)

Why did I have to read this at school.
Now I want to go home and try it out! If anyone else has any luck with this, post back. I'm interested in finding out, and I'll be back on later today in studyhall.
yaaaay~

Oh, it absolutely works with the new SDK update. No more vtex_dll.dll errors, they build just fine in Portal. And the peasants rejoice!yaaaay~
So no more of the crap where the game locks the mouse movement up and creates weird looking bloom effects where lights are? 

subsequent buildcubemaps will actually be included into the existing bsp
making the file even larger... I gleaned this info from the Valve Developer Wiki
a week ago, so I don't know the actual link, although looking up
Cubemaps from the main page might help to explain it.
Curious, I compiled it again under a different name to be sure it would be fresh. I opened it up with pakrat and found that there were actually placeholder cubemaps sitting there in the bsp already.
Lastly, I found something I forgot to do the first time, so I compiled it again. Due to my previously mentioned problems with changing the HDR settings, I accidentally compiled the HDR cubemaps twice. This did not increase the filesize at all.

That makes no sense! Time to email Mike Durand.
